The Special Court for Sierra Leone (SCSL) on April 26 convicted Liberia's former president Charles Taylor on all 11 counts of war crimes and crimes against humanity committed during Sierra Leone's decade-long civil war. Trial Chamber II found unanimously that Taylor aided and abetted Revolutionary United Front (RUF) and Armed Forces Revolutionary Council (AFRC) forces. Taylor is the first head of state to be tried and convicted by an international tribunal. The verdict was welcomed by the UN High Commissioner for Human Rights. A sentencing hearing is scheduled for May 16, and sentencing will take place May 30. The court may not impose the death penalty or a life sentence. Both the prosecution and the defense will have the opportunity to appeal within 14 days of the sentence.

The International Criminal Court (ICC) office of the prosecutor announced April 24 that it is monitoring the situation in Mali for potential crimes under the ICC's jurisdiction. The statement notes that Mali has ratified the Rome Statute, giving the ICC jurisdiction to prosecute war crimes and crimes against humanity that may have occurred since fighting began in January. The prosecutor's office said:

UN Special Rapporteur on Rights of Indigenous Peoples James Anaya will visit the United States from April 23 to May 4 to launch the UN's first ever investigation into the rights situation of Native Americans. Anaya will be looking into the rights of Native Americans, Alaska Natives and Native Hawaiians, and meeting with government officials throughout the nation. One main goal of his investigation is to determine how the Unites States' endorsement of the UN Declaration on the Rights of Indigenous Peoples in December 2010 has affected the rights of these groups, and what improvements may still be needed. Anaya will report his findings and make recommendations to US federal and state officials during his trip.

The Pentagon announced on April 19 that two Uighur detainees were released from the US detention center at Guantánamo Bay to be transferred to El Salvador, where they have chosen to resettle. They are being released pursuant to a 2008 order by the US District Court for the District of Columbia. An executive order issued in 2009 mandated review of the cases by the Interagency Guantánamo Review Task Force (IGRTF), and all six agencies on the force gave consent to release the two detainees. The US said it has worked with El Salvador's government to ensure that the two men arrive safely and are not harmed upon arrival, as well as to protect them against inhumane treatment at any stage of the transfer.

A Libyan military commander filed a lawsuit April 17 against former UK Justice Minister Jack Straw alleging that the minister was instrumental in his illegal rendition to Libya, where he was tortured under the regime of Moammar Qaddafi. Abdel Hakim Belhadj and his wife were transferred to Libya in 2004 as prisoners and were allegedly tortured at the hands of former Qaddafi officials. The lawsuit was launched in response to an April 15 Sunday Times report alleging documentation of Straw's involvement in the transfer of prisoners to Libya for torture. Papers served on Straw request access to documents from 2004 to 2010, including the documents referenced in the recent news article. Belhadj's lawyers maintain that his primary purpose is to seek an apology from the responsible parties.

The Supreme Court of the Netherlands ruled April 13 that the relatives of Bosnian men killed by Serb forces in 1995 cannot sue the UN for failing to protect them during the massacres. The ruling essentially held that the UN is immune from prosecution in Dutch courts. The group bringing the lawsuit, known as the Mothers of Srebrenica, are claiming that the UN is liable for their failure to protect civilians during the 1995 Srebrenica massacre. The UN is claiming that it is immune, citing Article 2 Section 2 of the Convention on the Privileges and Immunities of the UN, which says that the UN "shall enjoy immunity from every form of legal process except it has expressly waived its immunity." Both a District Court at The Hague and the Supreme Court agreed with the UN, but the Mothers of Srebrenica have said they plan to appeal to the European Court of Human Rights.

The US Department of Justice (DoJ) and Department of the Interior (DoI) announced a $1.023 billion settlement with 41 American Indian tribes April 11. The announcement comes following a 22-month negotiation period after the tribes charged in a class action that the DoI and the Department of the Treasury mismanaged money held in a trust account from natural resources on tribal lands. The DoI holds nearly 56 million acres in trust for Native American tribes, and leases much of these lands for various uses including timber, mineral, oil and gas extraction. Attorney General Eric Holder stated that the settlement "fairly and honorably resolves historical grievances over the accounting and management of tribal trust funds, trust lands and other non-monetary trust resources that, for far too long, have been a source of conflict between Indian tribes and the United States."

A Beijing court on April 10 sentenced Chinese housing activist and lawyer Ni Yulan to two years and eight months in prison on charges of fraud and "inciting a disturbance" in Beijing. Ni's husband, Dong Jiqin, was also sentenced to two years in prison on similar charges. Ni and her husband had assisted victims of government land seizures, including those displaced by the Beijing Olympics project, prior to their arrest in August 2011. Amnesty International called for Ni and her husband's immediate release, saying that that charges are false and meant to punish Yulan for her activist work. Ni has been confined to a wheelchair since 2002, when prison guards beat her severely while she was serving one of two prior prison sentences. In poor health, lying on a stretcher and relying on an oxygen machine, Ni pleaded not guilty at her trial in December. Although a court spokesperson indicated the trial was open to the public, foreign journalists and diplomats were barred from the proceedings.
